While availability may be poor, the overclocking performance isn’t. When fine tuning these memory modules we were able to reach a maximum stable frequency of 1872MHz, which is a healthy 17% overclock. Furthermore, when operating at 1333MHz we were able to tighten the timings up to CAS6-6-6-16, which was quite remarkable and showed the A-DATA X Series DDR3-1600X 6GB memory to be highly flexible.
